Perhaps you should try some spelling variations:
"present modeling algorithm" » "present making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "present model algorithm" (Expand Search), "patient modeling algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural finding algorithm" (Expand Search), "neural routing algorithm" (Expand Search)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh algorithms" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("present modeling algorithm") OR ((("element both algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present modeling algorithm\") OR (((\"element both algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( present modeling algorithm ) OR ((( element both algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present modeling algorithm") OR ((("element both algorithms") OR ("neural coding algorithm"))))*.
